[PATCH v2 0/4] Test fixes and debug logging

[Ian Rogers]

Testing in a hypervisor guest showed some issues that these patches
try to address, or improve the debug situation upon.

v2: Rebase. Tested Arnaldo repeat case on Intel but didn't repro,
    assume was fixed as part of the legacy metric json test fixes.

v1: https://lore.kernel.org/lkml/20250914182900.1960567-1-irogers@xxxxxxxxxx/

Ian Rogers (4):
  perf test: Be tolerant of missing json metric none value
  perf parse-events: Add debug logging to perf_event
  perf test: Don't fail if user rdpmc returns 0 when disabled
  perf stat: Display metric-only for 0 counters
